Ndombele, for all we know, could be trying his best to adapt, too. He may not have the work rate of a Fred, but that doesn't mean he's not listening to his manager and coaches. Only time will tell.
Also, imo, Fred getting away from José helped a bunch, too. If José was still here I don't think Fred would be as consistent as he is now. Fred did have a few good games under José, but he never settled because, at the drop of a hat, he'd be dropped and the toxicity José created probably made it harder to settle, too.
Agreed. Ndombele needs to show he's worth making said adaptions for certainly.
